Extinctions of aculeate pollinators in Britain and the role of large-scale agricultural changes

It is increasingly recognized that many pollinator populations are declining. Ollerton et al. looked at British historical distribution records for bees and flower-visiting wasps across the past century. Though it is well known that agricultural intensification after World War II had a negative impact on many species, pollinator declines began in the decades preceding this time, when other changes were made to agricultural practices and policies.
